McCullagh, who brings nearly 20 years’ experience to the role, will focus on strengthening Grant Thornton's VAT offering in the real estate and financial services sectors, and leading on the development of VAT automation.
He joins the firm from Mazars where he was a partner, specialising in indirect tax since September 2012.
Prior to that he spent 12 years at Deloitte most recently as VAT director.
He specialises in providing expert indirect tax advice and is a recognised figure in the tax environment, having been nominated by International Tax Review as one of the UK's leading indirect tax advisers for the past two years.
McCullagh said he was “excited” to be joining Grant Thornton’s tax team.
“This is a period of seminal change in the indirect tax world, both at a macro–economic and regulatory level. There are a number of factors that have the potential to alter the current landscape, including Brexit and the introduction of VAT regimes in the United Arab Emirates and Saudi Arabia. Combine these with the ongoing shift from direct to indirect taxation and we can see why indirect tax is becoming the fundamental tax issue for our clients.”
He added, “Grant Thornton's team of experts are in the perfect position to offer unique insights and expertise in order to support both UK and global businesses through these changes, and I am looking forward to working with them."
Clive Fathers, head of London tax at Grant Thornton added, “We are thrilled to welcome Vinny to the firm. Technology is starting to become a major disruptor in the tax arena and Vinny's extensive experience will be invaluable in leading the firm's VAT offering in this area.
“By identifying these key growth areas and continuing to invest in our people, through external hires and promoting our own internal talent, we can look to build on our on-going growth."
